COTTON TAMPER Filed July 16, 1937 3 Sheets-Sheet 3 if o a? ZJ/WYZ'eAV/Qy/Ma ATTORNEYS Patented Aug. 29, 1939 UNITED STATES ATENT OFFICE 1 Claim.

This invention relates to cotton tampers for compressing cotton into bales of a selected weight and has for the primary object the provision of a device of this character which will be rapid in operation, simple in construction and may be successfully driven by a minimum amount of power and will produce a maximum amount of pressing power on the cotton to compress the latter into bale form.

Another object of this invention is the provision of means for automatically feeding cotton into position for tamping in accordance with the movements of the tamper.

With these and other objects in view, this inver ion consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a front elevation partly in section illustrating a cotton tamper constructed in accordance with my invention.

Figure 2 is a side elevation, partly in section,

illustrating the same.

Figure 3 is a top plan View illustrating the device.

Figure 4 is a sectional view taken on. the line 44 of Figure 3.

Figure 5 is a reversing rack bar.

Figure 6 is a sectional view taken on the line 66 of Figure 5.

Figure '7 is a sectional View taken on the line 1-1 of Figure 2.

Referring in detail to the drawings, the numeral I indicates a main frame of any desired construction on which is secured a shaft mounting 2 having vertical guides to slidably receive a stem 3 of a tamper 4, the latter being arranged for vertical reciprocation and adapted to be associated with a baling frame or similar device to tamp cotton therein, a part of which is shown at 2'. The stem 3 has secured thereto relatively spaced pins 4' engaged by teeth of a gear 5. The rotation of the latter in opposite directions brings about reciprocation of the tamper 4. The tamper 4 includes a head 6 having yieldably secured thereto a face plate 1 adapted to engage with the cotton for the purpose of packing the cotton in a bailing frame or similar device 2. The gear 5 is secured to a shaft 8 and the latter is journaled in the mounting 2 and has secured thereon a reversing rack bar 9 of annular formation and provided with arcuately arranged and relatively spaced pins 9 and also provided with a double shaft slot ll] of arcuate shape presenting a pair of runs for a shaft II, the latter having secured thereto a pinion or gear I2 which meshes with pins 9. The shaft H is journaled in a frame I3 and the latter is hinged onto the mounting 2 by a power shaft I4, the latter also being journaled in the mounting 2 and having secured thereto a belt pulley I5 and a gear it which meshes with the gear I'I secured on the shaft II. The gear Il' is much larger than the gear It so that power delivered by the power shaft I4 will be increased to the shaft II. The pins 9 are mounted in a wall I8 of the rack bar 9' and are also connected by an arcuate shaped spacer I9;

Continuous rotation is imparted to the shaft II from the drive shaft I4 and the gear l2 thereof meshing with the pins 9 brings about rotation of the rack bar 9 in opposite directions and the latter being secured on the shaft 8 rotates said shaft in opposite directions and thereby brings about reciprocation of the tamper 4. A power source of any well known character and (not shown) is belted to the pulley I5. An idler pulley I6 is arranged adjacent the pulley I5 on which the belt may be placed when not desiring operation of the tamper with the power source in operation.

The frame I3 is free to swing so that the shaft II may follow the runs of the slot II! and pass about the ends of the spacer I9 and in order that the swinging movement of the frame i3 may be limited an adjustable check 20 is connected thereto and on the main frame.

A hopper 3G is mounted on the main frame I adjacent to the path of movement of the tamper and its discharge end is controlled by a gate 31 of substantially triangular shape in cross section and pivotally mounted at its apex, as shown at 38.

uppermost position and the hopper closed during the downward movement of the tamper.

What is claimed is:

A tamping apparatus comprising a supporting structure, a tamping element mounted for reciprocation. on said supporting structure and including a rack bar, a gear meshing with said rack bar, a shaft journaled on the supporting structure and having the gear secured thereto, an annular rack bar secured on said shaft and provided with a slot providing double runs, teeth forming elements providing part of said annular rack bar and arranged in annular formation adjacent the slot and having the runs thereof positioned at opposite sides of the teeth, a frame pivoted on the supporting structure, a second shaft journaled on said frame and extending into the slot of the annular rack, a gear secured to the second named shaft and meshing with the teeth of the annular rack, a power shaft journaled on the supporting structure, gears connecting the power shaft with the second named shaft, a cotton hopper carried by the supporting structure, a gate for controlling said hopper, an operating means actuated by the pivoted frame and connected with said gate for opening and closing the same in accordance with the movement of the tamper element.
